Hello, for about a week until today, my friend and I from different countries were having a higher ping (210ms ±) with mudfish to europe servers. Today it has gone back to being low again and good (180-190ms). I just thought i would let you know in case you can make sure it doesn’t change again. He is from Maldives, and I am from South Africa, and we connect to blizzard Europe for overwatch. So now it is fixed again 
We tried all the different nodes when it was bad and it didnt help. But now all nodes work well Thank you
No idea from mine what’s going on at the international submarine cable. 
Might be related for your case.
